    • An optical disk device includes a test recording portion, a power control portion, a recording portion and a power correction portion. The power control portion determines a first recording power to record recording information to the optical disk based on test information recorded by the test recording portion. The power correction portion calculates a first average of modulation of the recording information recorded on a first track of the optical disk at the first recording power and a second average of modulation of the recording information recorded on a second track of the optical disk at the first recording power. The power correction portion increases the first recording power to a second recording power when the second average of the modulation drops below a first threshold value that is preset and drops below a second threshold value that is calculated based on the first average of modulation.
